1. Dispensing device for delivery of items of candy, tea, coffee beans, nuts or the like, said dispensing device comprising: a stationary container having a lower section with a semi-cylindrical inner periphery and a longitudinal axis (A), said container furthermore comprising transverse downstream and upstream sections and a dispensing opening arranged in the downstream section of the container;a conveyor screw rotatably arranged around the longitudinal axis (A) in the lower section of the container to feed items towards the dispensing opening;drive means that, when activated by a lever or button, rotates the conveyor screw; wherein said conveyor screw comprises a downstream and an upstream member arranged transverse to the longitudinal axis (A) and rotatably supported in the corresponding downstream and upstream section of the container, said downstream and upstream member having an outer periphery and a radius smaller than the semi-cylindrical lower section of the container, said conveyor screw furthermore comprising at least two elongated rods extending helically from the outer periphery of the upstream member arranged in a first angular position in relation to the longitudinal axis A to the outer periphery of the downstream member arranged in a second angular position in relation to the longitudinal axis A, said first angular position and said second angular position are different and said first angular position is arranged at an angle (α) advance to the second angular position when seen in the direction of rotation of the conveyor screw, and wherein a feeding adjustment plate is arranged transverse to the longitudinal axis (A) between the downstream transverse member and the dispensing opening, said adjustment plate rotates together with the conveyor screw and comprises one cut-out portion for each elongated rod of the conveyor screw, said cut-out portions have a size and shape that is adapted to the size and shape of the items within the container to adjust the feeding of items from the container. 2. Dispensing device according to claim 1, wherein the elongated rods each has a circular, oval, rectangular, flat or angled cross sectional shape. 3. Dispensing device according to claim 1, wherein the positions of the elongated rods around the outer periphery of the upstream and downstream member are symmetrically distributed. 4. Dispensing device according to claim 1, wherein the dispensing opening in the downstream end of the container is arranged at an angle ω from a vertical plane through the longitudinal axis (A) so that the items in the container must be lifted by the conveyor screw to the dispensing opening, said angle ω is within the range of 45° to 110°. 5. Dispensing device according to claim 4, wherein the dispensing device furthermore comprises an intermediate plate arranged between the downstream transverse member and the downstream section, and said dispensing opening is formed by an edge of said intermediate plate and said edge is arranged at the angle ω from the vertical plane through the longitudinal axis (A). 6. Dispensing device according to claim 1, wherein the longitudinal axis of (A) of the container is inclined an angle Ø in relation to a horizontal plane (H) and the downstream end arranged at a lower vertical position than the upstream end of the container, said angle Ø is within the range of 2° to 15°. 7. Dispensing device according to claim 1, wherein a lifting device is arranged in the area defined between the downstream end of the elongated rods and the downstream transverse member, said lifting device lifts the items in the container to the dispensing opening. 8. Dispensing device according to claim 7, wherein the lifting device is a triangular plate arranged between the downstream transverse member and the downstream end of the elongated rods. 9. Dispensing device according to claim 8, wherein the size of the lifting device is adapted to achieve the desired feeding of items from the container. 10. Dispensing device according to claim 1, wherein the elongated rods extending between the upstream and downstream transverse member are arranged a distance from the inside surface of the container.
